Fair enough. Microsoft is demanding no ARM-based platform running Win8 can have their locked-down boot mechanism disabled. In other words, Microsoft is demanding manufacturers make machines that can only run software Microsoft allows them to run.
Or a market opportunity. Hard to say -- in many respects, the standardized PC is a fluke, created through clean-room reverse engineering and the resulting clone market.
Nicely put. Also, another huge factor in the standardized open PC was Microsoft licensing DOS to Compaq. That triggered the PC clones and the PC revolution which Linus leveraged with Linux and then Apple a decade and half later.
> Microsoft is mandating that the user must have the option to disable secure boot via firmware switch
They are not mandating it one way or the other. <sarcasm>In their infinite benevolence</sarcasm> they leave that at the discretion of x86/AMD64 machine makers. For now.
They do not for ARM machine makers that want to run Windows.

Wrong. The Windows 8 logo requirement specifically mandates that secure boot can be disabled by the end user, or (perhaps and...not sure on the correct conjunctive) that the end user can add new keys.
The opposite is true of ARM, however.
